The general formula is MeCO3.
It is KHCO3
Feldspar and quartz are not carbonates (carbonate minerals). They are silicates because they have Silica (Si) in the formula. Quartz is SiO2. Feldspar is a mineral group (feldspars) They have a variable composition that gneerally depends on the amount of Ca, Na or K in their chemical formula. An example of feldspar is Albite NaAlSi3O8. Carbonates have CO3 in their chemical formula. Two examples are Calcite (CaCO3) and Siderite (FeCO3).
MeCO3 where Me is a metal.Ex.: sodium carbonate, potassium carbonate, magnesium carbonate, uranyl carbonate, etc.
Lead carbonates are PbCO3 and Pb(CO3)2; lead (5) carbonate doesn't exist.
Carbonates react with hydrochloric acid.
As carbonates are mildly basic, anything acid will react with them (releasing carbon dioxide gas).
The acid that makes carbonates is carbonic acid.
Aragonite is a common carbonate mineral that is a polymorph of calcite. It is classified as a member of the aragonite group and belonging to the class of carbonates.
No, carbonates do not contain silicon. Carbonates are composed of carbon and oxygen, typically combined with a metal such as calcium, magnesium, or iron. Silicon is a separate element found in silicate minerals.
Calcite belongs to the carbonates.
No, any strong acid will react with carbonates.
The salts of carbonic acids are called bicarbonates (or hydrogen carbonates) and carbonates.
